Inventions I (Probably) Won't Make

It's that time of year again when the heel on my right shoe is in desperate need of repair or replacement. Unfortunately, shoes are not designed to be easily repaired in 2018. They need to be replaced, often because of damage to one area of the shoe. This is incredibly wasteful and, looking at the heels of shoes worn by other men in the area, a common problem that should be solved with better products. How hard would it be to develop a new pair of shoes that have heels that can be replaced with minimal effort and cost?

In addition to this idea, I also explain my frustration with umbrellas and the desire to build a better one. Problem is, I likely will not create a new shoe or umbrella. I have neither the expertise nor resources to make either happen.
